MEANS FOR AUTOMATICALLY SUPPLYING WATER TO TANK S.

SPECIFICATION forming part of Letters Patent No. 659.015, dated October 2, 1900.

' Application filed August 4, 1900 serial No. 25.8%. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. CLARK, a citizen of the United States, residing at Springfield, in the county of Hatnpden and Stat e of Massachusetts, have in vented certain new and useful Improvements in Means for Automatically Supplying Water to Tanks, &c.; and I do hereby declare that the following is'a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its object to provide a simple and effective means for antomatically supplying tanks, troughs, and other like vessels with water and in which the supply and shut-off mechanism will be positive in its action and at the same time free from hammering and noise and that will take the place of the ordinary ball-cocks or tank-supply valves and will successfully operate without the necessityof leather, rubber, or other like packing usually found necessary.

The invention consists in an automatic water-supply or service valve for tanks constructed substantially as shown in the draw ings and hereinafter described and claimed,

Figure 1 of the drawings is a sectional elevation of a portion of a tank, trough, or other like vessel, showing in elevation the watersupply mechanism connected thereto; Fig. 2,

a sectional elevation, on an enlarged scale, of the water-supply valve and its connections.

In the accompanying drawings, A represents a portion of a tank, trough, or other. like vessel for containing Water to which my improved supply-valve is connected. The bottom of the tank or other vessel is provided with an exterior screw-threaded couplingpipe B, to which is connected the usual pipe} 7 The upper end of this coupling-pipe B terminates in a:

leading to the source of supply.

flanged seat 0, the flange a. thereof having an interior screw-thread for coupling thebody D'f thereto, which body forms the outer casing of flange a and the interior screw-threads e11- gaging the threads on a support E to hold it in place. A'packing-ringc is interposed between the seat 0 and the flange b, and packiugs d e are interposed between the seat 0 and bottom of the tank or other vessel and a nut f to form a tight joint, as found necessary.

The support E is dish-shaped, as shown at h, and has a plurality of perforations g for the passage of the water, the support also having an upturned flange '5, against which the packing-ring 7c abuts.

The valve-casing F is frusto-conical in shape, its lower end resting upon the packing-ring k, said casing having perforations l for the passage of the water.

The hollow body D has a contracted neck m and an openingn at its top for the discharge of the Water, a packingo being interposed between the top of the hotly D and the upper end of the valve-casing F, the water and air escaping through the opening atthe upper end of the body.

A frusto conical valve-plug Gworks in the valve-casing F, said plug being connected in any suitable manner to a tubular stem H, but preferably by the nuts 13 q, engaging the screw-threads on the tubular stem. The tubular stetnH has perforations or passages r for the escape of the water and air against a deflecting-hood I, which hood extends down over the upper end of the hollow body D, as shown in Fig. 2 of the drawings.

The hood I is suitably connected to the upright rod K or supported above the upper end of'the body D in anydesirable manner found best adapted to the purpose. This rod K has connected therewitha suitable lever L, to one end of which is a globular or other suitable float M and the opposite end of the lever is pivotally connected to a bracket N upon the tank or vessel. A coupling 0 is pivotally connected to the upper end of the rod K, and through this coupling extends the lever L, which is held thereto by a set-screw s. The two pivotal connections comprising the point of attachment. between the lever'L and coupling O and that between the lever and the bracket N enable the float and lever to perfectly operate by the rise and fall of the water in the tank or other vessel. The rod K is connected to the upper end of the tubular stem by screw-threads thereon engaging with screw-threads in the end of the tubular stem, and the hood K is shown as connected to the rod in asimilar manner. I do not wish, however, to be understood as limiting myself to any special form of hood or of any special form of float, and when found necessary the float maybe connected directly to the rod, as shown in dotted lines of Fig. 1 of the drawings.

The general construction of the parts is susceptible of many changes and modifications without departing from the principle of the invention, and the valve and its connections may be applied to any tank or vessel wherean automatic supply of water is found desirable through the medium of a tank-service valve.

The supply and cut-off mechanism comprising the automatic supply-valve and its immediate connections, as shown in Fig. 2 of the drawings, is self-cleaning and no dirt or grit can rest between the valve-casing F and the valve-plug G, and any part of the device may be renewed at anytime without the sacrifice of the other parts, this being considered of material importance in water-supply valves to tanks or whereacontinuous supply of water is desired.

The valve-casing F and the valve-plug G are preferably ground together, and although closing against the pressure of the water the angle of impingement of the pressure is such that but small force is required to close the supply of water through the perforations in the casing F, and at the same time the pressure of the Water between the cylinder and the plug prevents the plug sticking against the interior of the casing. There being no packing between the plug and interior of the valve-casing required the necessity of the continual renewing of the packing after it becomes worn and worthless is entirely avoided. The tubular stem H provides means for the passage of the airand water,and thereby removes the necessity of a cushion at the bottom of the valve-plug, which would otherwise be necessary if not relieved by providing an outlet for the water besides that between the valve-casing and the valve-plug. As the height of water in the tank or vessel becomes lower the float M will drop and through its connection with the plug G the plug will be forced down and the perforations Z in the valve-casing F will be opened, thus allowing the water to pass up through said perforations.

The valve is shown as closed in Fig. 2 of the drawings, and when the valve-plug is forced down, as previously stated, the water will pass up through the pipe-coupling B through the perforations g in the support E, and thence up between the hollow body D and valve-casing F and through the perforations Z and pass out through the opening in the top of the body D. As the water thus escapes it will impinge against the sides of the hoodI and be directed thereby to the bottom of the tank or vessel, thereby directing the flow of water in its course after it leaves the valve and preventing the inflowing stream from spattering out of the tank and also silence all noise due to the influx of the liquid.

The water-supply device and its connections may be conveniently attached to any tank or vessel in place of the old form of ballcocks or supply-valves with comparatively little trouble and will work perfectly in automatically supplying water to a tank or vessel wherever a source of supply is available.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Means for automatically supplying water to tanks, troughs, and other vessels, consisting of an outer casing having an opening at its upper end for the discharge of water, a perforated valve-casing located in the outer casing, a water-passage between the outer casing and valve-casing, a perforated support for the lower end of the valve-casing detachably connected to the interior of the outer casing, avalve-plug adapted to work in the valve-casing, a tubular stem connected to the plug and having perforations at its upper end for the discharge of water, a suitable rod connecting with the tubular stem, and a float connecting with the rod, substantially as and for the purpose set forth.

2. Means for automatically supplying water to tanks, troughs, and other vessels, consisting of a coupling-pipe having a flanged seat, and outer casing connected thereto and having an opening at its upper end for the discharge of water, a perforated support detachably connected to the outer casing, a perforated valve-casing seated upon the support, a valve-plug adapted to work in the valvecasing, atubular stem connected to the valveplug and having perforations near its upper end, a deflecting-hood extending down over the upperend of the outer casing, and a suitable float connecting with the valve-plug,substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

WILLIAM E. CLARK.
